Kristen Wiig and Strokes drummer Fabrizio Moretti have split after 18 months together. They began dating in December 2011, when Page Six spotted them “all over each other” at a Black Keys party. But Us Weekly reported last week that the couple we’d dubbed “Wiigetti” has called it quits, although things are “very amicable.” Wiig, who left “SNL” in 2011, said last summer in Marie Claire, while dating the rocker, “I’m happier than I’ve ever been, and I feel very lucky right now.” She’s currently in the indie film “Girl Most Likely.”
